Hello. So recently I had a bunch of spreadsheets in separate files, and I grouped them all together back by coding the individual files using numbers (1,2,3 and etc.), copying one set of data by having one spreadsheet opened (say spreadsheet 1 into the 1st column of my master spreadsheet), then dragging that data in the master to match the number of files I wanted (about 30+), then manually find and replace each column so that I change the spreadsheet in the formula (eg. 1 to 2 in 2nd column, 1 to 3 in 3rd column). Now this was about 30+ files so it was not too bad to do manually. But in the future I may have to do the same task about a 100+ files and that would be a bit overkill to be honest. Is there some magic formula or macro I can do to get around this task more easier?
